first you have to find the sum of angles and sides. then subtract 2 which is 18 and multiply 18 times 180.

What is the measure of one angle of a regular 20-gon?

The measure of one interior angle of a regular polygon with 20 sides is 162°.The general rule to find the measure of the interior angle of a polygon with n sides is:( n - 2 ) * 180° / nIn the case of our 20-gon, n equals 20, so...( 20 - 2 ) * 180° / 2018 * 180° / 203240° / 20162°

Interior angle and each exterior angle of a regular 18-gon?

Interior angle measure of a 18-gon = [180⁰(18 - 2)]/18 = 10⁰(16) = 160⁰. Exterior angle measure = 180⁰ - 160⁰ = 20⁰.


Measures of an exterior angle of 20-gon?

Well, honey, an exterior angle of a polygon can be found by dividing 360 degrees by the number of sides. So for a 20-gon, each exterior angle would be 18 degrees. It's as simple as that, darling.


What is the measure of each exterior angle of a 20 gon?

If it is a regular polygon then each exterior angle is 360/20 = 18 degrees


What is the measure of each exterior angle measure of a regular 18-gon?

360/18 = 20 degrees


What is the measures of one exterior angle of a regular 18-gon?

The measure of one exterior angle of a regular 18-gon is 20°. The sum of all exterior angles of a regular polygon is always 360° so the measure of each exterior angle can be calculated by dividing 360° by the number of sides. In this case that would be: 360° 18 = 20°Therefore the measure of one exterior angle of a regular 18-gon is 20°.
